Could a 14 Year Old Male pull this off?

If you are dedicated as you say you are I personal highly suggest P90X. Yes it does cost some money but with yard work for two or three weeks it can be done. You will achieve the results you want and more. But to get a six pack your way it is more then just eating right. Its what you eat, when you eat it,how much, and how much you are taking in. What I mean how much you are taking in like fats,carbs, sugars, etc. If you know a nutritionist through friends, family, or maybe even your school ask them for help.
